The DJI Mic Mini 2S is a compact two-person wireless microphone system that adds 32-bit float internal recording, AI noise cancelling, and support for up to four transmitters. Building on DJI’s lightweight Mic Mini range, each transmitter provides 14.5GB of usable storage for up to 28 hours of 24-bit recording. Up to 400m transmission gives subjects more room to move, while Adaptive Gain Control helps manage sudden or uneven speech levels. The redesigned charging case keeps the system together for storage, charging, and file transfer. The included Multi-Colour Magnetic Cover Set adds eight interchangeable finishes, giving more control over how discreet or visible each transmitter appears on camera.
What’s new?
The DJI Mic Mini 2S succeeds the DJI Mic Mini 2, advancing the Mini line by adding internal recording to each transmitter, including 32-bit float capture for greater recovery latitude when levels change unexpectedly. Its 14.5GB usable storage provides up to 28 hours of 24-bit recording, so the transmitter can maintain a local backup if the wireless signal drops. A new AI noise-cancelling system separates speech from surrounding sound more precisely, while Adaptive Gain Control manages sudden peaks or changing voice levels before they become harder to correct in post.
The receiver now connects to up to four transmitters, extending the system beyond two-person recording without moving to a larger wireless setup. Quadraphonic output keeps four sources separate through supported Sony camera or USB connections, giving each speaker an independent track for editing. The redesigned charging case also adds space for the Mic Series Mobile Receiver and supports direct transfer of internal recordings, reducing the number of separate accessories needed for charging, storage and file offload. The system can therefore expand to larger multi-person recordings while retaining the compact format of the Mic Mini range.
Internal recording and file security
Each DJI Mic Mini 2S transmitter includes 14.5GB of usable internal storage, giving the microphone its own recording path alongside the wireless feed. It stores up to 28 hours of 24-bit audio or 22 hours in 32-bit float, providing a local copy if transmission is interrupted. Automatic recording can begin when the transmitter powers on or connects to the receiver, while a low receiver battery can also trigger an internal backup. Loop recording keeps the system running by replacing the oldest files once storage is full.
32-bit float recording provides greater latitude when speech levels change sharply, reducing the need to monitor gain continuously. Internal files can be saved as the untreated Original File or as an Edited File with selected processing applied. This allows users to retain a clean source for post-production or work with audio that already includes noise cancelling, voice tone, low cut and gain processing. Recordings can also be transferred through the charging case at up to 34MB/s.
AI noise cancelling and level control
A dedicated NPU drives the Mic Mini 2S AI noise-cancelling system, allowing the transmitter to distinguish speech from surrounding sound before applying suppression. Basic mode reduces lower-level background noise such as ventilation and room reverberation, while Strong mode applies heavier reduction where environmental sound is more prominent. The processing can be controlled from the transmitter, DJI Mimo app, or compatible OsmoAudio devices. This reduces the amount of background noise that needs attention in post-production.
Adaptive Gain Control helps keep speech levels under control as volume changes. Clipping Control steps in when a voice suddenly gets louder, while Loudness Balance smooths out quieter and louder sections for a more even result. Regular, Rich and Bright voice presets give some simple tonal control, and a 100Hz low-cut filter helps reduce low-frequency rumble.
Four-transmitter wireless system
The Mic Mini 2S Receiver expands the compact system to support up to four compatible Mic Mini-series transmitters at once. This allows a single receiver to handle larger conversations, panel discussions or podcasts without requiring a separate receiver for each pair of speakers. Wireless transmission reaches up to 400m with compatible Mic Mini-series transmitters, giving subjects room to move while maintaining the receiver link. Cross-generation support also allows Mic Mini and Mic Mini 2 transmitters to join the same receiver setup. This makes the system easier to expand gradually rather than replacing compatible existing transmitters.
Channel routing changes with the number of speakers and the required edit. Mono combines connected microphones, Stereo separates them across left and right groups, and Quadraphonic keeps four transmitters independent through supported digital connections. Four-channel output is available through compatible Sony cameras using the separately available DJI Mic Series Camera Adapter, or through supported computer software over USB. This gives each speaker a separate track for level, tone and timing adjustments in post-production. Safety Track is also available in Mono, creating a second combined channel at 6dB lower level. The 3.5mm output remains stereo in Quadraphonic mode, combining TX1 and TX3 on the left channel and TX2 and TX4 on the right. These routing options allow the same receiver to serve straightforward recording or more involved multi-speaker editing.
Compact mounting and operation
Each Mic Mini 2S transmitter weighs 12g and can be attached using either the magnetic clip or included magnet. The detachable clip supports four mounting directions, helping to keep the microphone oriented towards the speaker when attached to collars, lapels or other clothing. An omnidirectional pickup pattern maintains consistent speech capture as the wearer moves naturally, while the supplied windscreen reduces wind reaching the microphone outdoors.
The transmitter also uses interchangeable magnetic front covers, with Obsidian Black and Glaze White supplied as standard. This bundle adds the DJI Mic Mini 2S Multi-Colour Magnetic Front Cover Set, providing eight further finishes: Iris Purple, Starry Blue, Azure Blue, Misty Teal, Pine Green, Golden Yellow, Sunrise Orange and Blush Red. Each cover attaches magnetically, so the transmitter’s appearance can be changed without altering its mounting position. A dedicated storage case keeps the additional covers together when not in use.
Device connectivity and OsmoAudio
The Mic Mini 2S Receiver connects to cameras through 3.5mm analogue audio and to phones, tablets and computers through digital USB connections. Camera power synchronisation allows the receiver to switch on and off with compatible cameras, reducing the chance of leaving one device running separately. When connected to a phone, the receiver can remain attached during speaker playback and can accept external power while the phone is charging. This supports conventional camera, computer, and mobile recording setups from the same receiver.
OsmoAudio removes the receiver entirely when working with compatible DJI devices. Up to two Mic Mini 2S transmitters can connect directly, with settings available through the connected DJI camera. The transmitters can also synchronise internal recording with the camera’s recording status, maintaining a local backup alongside the direct audio feed. Bluetooth provides a further direct connection to compatible smartphone applications using one transmitter. The transmitter remembers two receivers and one compatible OsmoAudio camera, reducing the need to repeatedly pair devices.
Charging case and power management
The charging case powers two transmitters and the receiver while keeping the complete recording system stored together. A full case provides around 3.2 complete charges for the set, extending total operation to up to 40 hours. Each transmitter runs for up to 11 hours and the receiver for up to 10 hours before returning to the case. Fast charging provides up to one hour of use from five minutes of charging. This allows short charging periods to cover additional recording time when a full recharge is unnecessary.
The case also handles more than power. Opening it powers on and pairs the stored transmitters and receiver, while closing it begins charging after use. Its revised internal layout holds the receiver, two transmitters, a Mic Series Mobile Receiver and the principal mounting and connection accessories. Internal recordings can also be copied from the transmitters while they remain inside the case. This reduces the number of separate steps required between packing, pairing, charging and transferring audio.

FAQs:
Can the DJI Mic Mini 2S record more than two people simultaneously?
Yes. This kit includes two transmitters and one Mic Mini 2S Receiver, allowing two people to be recorded at the same time. Stereo mode assigns the transmitters to separate left and right outputs, while Mono mode combines them into one channel. The receiver supports up to four compatible Mic Mini-series transmitters when additional units are added. Quadraphonic mode provides four independent channels through compatible Sony cameras using the separately available DJI Mic Series Camera Adapter, or through supported computer software over USB.
What happens if the wireless connection is interrupted?
Each transmitter contains approximately 14.5GB of usable internal storage, so it can create an independent local recording while transmitting audio. At the default 24-bit setting, storage provides up to 28 hours of recording, while 32-bit float provides approximately 22 hours. If the receiver connection drops during automatic recording, the transmitter continues recording internally. Loop recording can overwrite the oldest files when storage becomes full. This architecture provides a separate audio source that can be synchronised during editing.
How does 32-bit float internal recording work?
The transmitter records 32-bit float WAV files to its internal storage when the mode is enabled through the DJI Mimo app. The format retains a wider dynamic range than the default 24-bit mode, allowing high or low recorded levels to be adjusted with greater latitude in post-production. It does not remove the physical limits of the microphone capsule or prevent every form of distortion. Enabling 32-bit float reduces the available recording duration from approximately 28 hours to approximately 22 hours. The feature is disabled by default.
Which devices are compatible with the DJI Mic Mini 2S?
The receiver supports compatible cameras, smartphones, tablets and computers through its analogue and digital connections. The supplied USB-C adapter connects it directly to supported mobile devices, while the 3.5mm TRS cable provides an analogue camera connection. Compatible OsmoAudio products can connect directly to up to two transmitters without the receiver. Direct Bluetooth phone use supports one transmitter and depends on the phone and recording application. Compatibility should be checked against DJI’s current device lists before use.
How long does the DJI Mic Mini 2S operate between charges?
Each transmitter provides up to 11 hours of operation, while the receiver provides up to 10 hours. The charging case replenishes two transmitters and one receiver around 3.2 times, extending total operation to up to 40 hours. Fast charging provides up to one hour of use from five minutes of charging, while the case itself takes around two hours to recharge.
